Thanks for contributing this Mark, that is a very useful addition to my collection, but sail design has changed since that plan was drawn and for single handing I find the best arrangement is a No. 3 with the same overlap but the luff should be full hoist to maximise the drive from the leading edge.
I have one of these on hanks and it is both effective and manageable. I am going to adapt it for the furler.
